Milkman Moby is giving milk to the poor. They need it for strong bones. He is also teaching them the word of God. Every man must have a strong mind. For every one that useth milk is unskillful in the word of righteousness: For he is a babe (Heb. 5:13). Those that are babes and are unskillful in the word of righteousness must be fed with milk. Milkman Moby is giving milk to drink. However in the word of God, he is giving the gospel milk. There is milk for the soul and body.
